BALL DAB RIG This Ball Dab Rig is highly productive and fun. The four large percolator holes on the "circ perc" really get the bubbles fired up around the interior ball. The inner ball also deflects the splash from making it up the mouthpiece. The airflow, function, and visual theatrics with this one are strong! PRODUCT DETAILS: 14mm Female Joint Circ Perc (Four Large Holes) Small Form Factor Height: 8.00” Tall Base: 3.00” Diameter Thick Borosilicate Glass
